freebsd stable - Oct 2011 - MPS LSI Driver status FreeBSD9 Beta3?

hi,

does anybody use the mps driver (if available) with Release9-Beta3?

the mps driver from 8.2 has problems with two paths over a LSI SAS 6160
Switch. eg. timeouts ... . Workaround: poweroff the second switch.

So it's interesting how stable/far the mps is from FB 9 Beta3

Denny, I don't have the same hardware so cannot test, but I only see a
couple of changes committed to HEAD not MFC'd  back to 8-STABLE:

http://freshbsd.org/commit/freebsd/r225950 (significant CAM changes)
http://freshbsd.org/commit/freebsd/r226118 (zeroing SCSI sense, probably minor)

This was only a cursory check; you can spelunk around yourself more here:
